Sevcon is a world-leading electrical engineering company based in Gateshead in the UK, that manufactures controls for electric vehicles. ==History== It was founded in 1961 as Sevcon Engineering Ltd. The company was formed to develop technology originated by Horace William Heyman (13 March 1912 - 4 September 1998), who had been Managing Director of Smith Electric Vehicles from 1949 until 1964. It was the largest manufacturer of electric vehicles in Europe. His technology improved battery-life for frequent start-stop runs of electric vehicles at low speeds. There were always large electrical losses on starting an electric vehicle because of electrical resistances heating up. The technology allowed a 20% reduction in battery size for equivalent power, or increased battery length or power for a standard-sized battery. An electric vehicle would have had resistances to drop the voltage on the motor when starting, but this created heating. His technology employed semiconductor-controlled rectifiers, with a semiconductor oscillator, which provided pulses of electrical power to power the motor. It won the Queen's Award to Industry in April 1970, and the Queen's Awards for Export in April 1975. A new factory opened in June 1970 at Gateshead. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sevcon」の詳細全文を読む スポンサード リンク
